I upped some KI-67's earlier and went on a bombing run. I lost one of my drones over the base due to ack and RTB'd with two planes. I landed and tried to stop with no luck. I slowed all of the way down but just kept sliding off of the runway. I couldn't end sortie because I was still moving. I dropped flaps, tried brakes, killed engines and nothing worked. I wasn't moving fast, just sort of sliding like there was ice on the runway. I finally had to start engines again and run into a hangar to stop. And only that worked after I hit BOTH engines on the side of the hangar. I took a vid but left it on my work comp so I will send it in tomorrow.
